Brake controller and 4x4 switch.
Not so much left over. All (or most) main wiring harnesses are the same. If the truck is not optioned with the particular option, it's just not used. Much easier to manage one spec of harness, from a mass production standpoint.Are they just left over from a wire harness? I have a 2WD.
